Abstract : Ecological sustainability and social equity are among the United Nations' Millennium Development. Goals - but, unfortunately, as the years pass, they are still far from being reached. But concern about these issues has made its way to industry and the IS community. IS play a central ro le in companies as they are cross - functional and have a strategic role in our current information society.

This article proposes Commoning and Common Information Systems as a possible tentative to facilitate the inclusion of both ecological sustainability an d social equity concerns within the IS discipline. We advance this new concept of Common Information Systems, which are IS where (1) the surrounding society is considered a human community, (2) the material and energy input into the IS are seen as common g oods, and the material and energy leaving the IS are viewed as common bads, (3) commoning (i.e. sharing) information output is preferred
